needed, to the skate runner to sharpen the same.

One of the important objects of the invention is to provide a sharpener which comprises a guide member having a longitudinal slot of a size to fit the runner of the skate, and wherein said guide is made in difierent sizes to fit the various widths of skate runners.

Another object of the invention is to provide a skate sharpener device wherein the skate runner can be honed hollow and wherein the side profile of the skate runner will not be subject to abrading or honing.

Still another object is to provide a sharpener of the character described which is of simple construction and wherein the guide as well as the honing stone or abrading member is replaceable, and wherein the parts may be made in different sizes and sold or distributed along with the particular skate when the same is purchased from the retailer.

These, together with various ancillary objects, features and advantages of the invention, which will later become apparent as the following description proceeds, are attained by the present invention, a preferred embodiment of which has been illustrated, by way of example only, in the accompanying drawings, wherein:

Figure 1 is a perspective view of skate shoe or boot illustrating a sharpener embodying the principles of this invention applied to the runner or blade thereof;

Figure 2 is an elevational view, looking at one end of the device and showing same applied to a skate blade;

Figure 3 is an end elevational view, looking at the other end of the device; and

Figure 4 is a longitudinal sectional view through the device, taken substantially on the line 4- l of Figure 2.

Referring now more particularly to the accompanying drawings, wherein like numerals designate similar parts throughout the various views, the numeral ll! designates a runner of a skate which is suitably fixed to the brackets 12 fastened to the body of a shoe or boot M in the conventional manner. A sharpener, constructed in accordance with the present invention and illustrated generally at I6, is shown in position for sharpening the skate runner in Figure 1.

The sharpener illustrated in the drawings, comprises a cylindrical guide member or holder I8 having a bore 20 for receiving an abrading member or honing stone 22. This guide member I8 is preferably made of metal such as a low carbon steel rod having a hole drilled therethrough slightly off-center. The member I8 includes a substantially conical open end portion 24 which facilitates turning or rotating the stone 22 with the thumb and fingers of the hand which holds the device. To receive the skate blade ID a longitudinal slot 26 is provided in the guide 3 which slot is of sufficient size to accommodate the ice skate blade the full length of the guide, the walls 28 of the slot being perpendicular to the central opening or bore 20. The offset bore 26 does not extend completely through the guide [8 and provides a stop portion 30 for receiving the end of the honing stone 22. A small aperture 32 in the portion 30 of the guide or holder l8 communicates with the slot 26 to permit the skate runner to ride on honing stone.

The honing stone 22 is in the form of a rod, as shown and arranged to be inserted into the bore 20 of the guide and adjustably held in position for sharpening the skate blade by the thumb or fingers of the operator. Preferably the metal guide member I8 is plated with chromium or cadmium to render it rust-resisting. Other coatings, such as vitreous enamel, plastic or resinous compositions may be utilized to protect the guide member against the elements as well as provide a sharpener having a pleasing appearance.

In the use of the sharpener, a guide will be selected having a slot to fit the particular skate runner or blade. The honing stone which is preferably first coated with light machine oil is inserted in the bore of the guide. The honing stone is then held in the guide with the forefinger and thumb and applied to the runner which is inserted in the slot 26. The guide with the honing stone held in place will then be passed back and forth over the skate runner while turning the stone with the thumb and forefinger when the same shows loading.

In this manner the runner of the skate will be honed hollow, whereas the side or profile of the runner is unchanged so that the edges of the blade remain straight and sharp cornered. When the blade of the skate is crooked, the same may be suitably straightened before insertion in the sharpener guide so that the blade will not bind in the roove of the guide. After applying the sharpener to the skate blade, the sharpness can be tested by application of the fingers or by running the skate blade over several thicknesses of paper, and when two distinct and sharp lines appear on the paper, the skate is sharpened. After use the honing stone may be cleaned by wiping it with a cloth or rag moistened with light machine oil.

In the light of the foregoing description it will be seen that a very simple and economical sharpening device has been provided for conditioning skate runners. A sharpener further, is provided wherein a skate may be honed hollow without the need of special machinery employing a skilled operator.

Having described the invention, what'is claimed as new is:

A skate blade sharpener comprising an elongated, rigid cylindrical holder formed from a single piece of metal and having an off-center bore extending longitudinally thereinto from one end thereof to a point in spaced relation to its other end; said holder further having a longitudinal slot in its thickest peripheral portion extending from end to end thereof and communicating with the bore, and a freely rotatable and reversible abrasive rod removably mounted in the bore, said rod being of uniform diameter and of a. materially greater length than the bore and projecting from said one end of the holder for manual rotation between the thumb and fore-finger of the hand in which the holder is held, said one end of said holder being substantially frustoconical.
